Winter Maintenance Tips: Protecting Your Pressure Washer from Frost Damage


As the winter season approaches, it’s essential to take proactive steps to protect your pressure washer from potential frost damage. Freezing temperatures can wreak havoc on the internal components of your machine, leading to costly repairs or even the need for a replacement. In this blog post, we’ll discuss the importance of draining your pressure washer before winter, highlight the signs of frost damage, and emphasize the benefits of contacting us for professional repair or replacement services.

Why Draining Your Pressure Washer Matters

Draining your pressure washer is a critical maintenance step before the cold weather sets in. Water left in the machine’s system can freeze and expand, causing irreversible damage to internal parts such as pumps, valves, hoses, and fittings. By draining the water completely, you eliminate the risk of freezing, ensuring the longevity and optimal performance of your pressure washer.

Signs of Frost Damage

It’s crucial to be aware of the signs that indicate your pressure washer may have suffered frost damage. If you notice any of the following symptoms, it’s time to take action:

  1. Unusual Noises: If your pressure washer starts making strange grinding, rattling, or clunking sounds, it could indicate damage caused by frozen water.
  2. Low Pressure or Loss of Pressure: Frozen water can lead to blockages and restrict the flow of water, resulting in reduced or no pressure during operation.
  3. Leaks or Cracks: Extreme cold temperatures can cause water to freeze and expand within the pressure washer’s components, leading to cracks or leaks in the system.
  4. Failure to Start: Frost damage may prevent your pressure washer from starting or cause intermittent starting issues.
  5. Unresponsive Controls: If the controls on your pressure washer become unresponsive or malfunction, it could be a result of frost damage affecting the electrical components.

Contact Us for Repair or Replacement

If you suspect that your pressure washer has experienced frost damage, it’s crucial to seek professional assistance promptly. Attempting to repair the machine yourself can worsen the problem or void any warranty coverage. At P C Jones Industrial Cleaning Equipment, our experienced technicians specialize in diagnosing and repairing pressure washers affected by frost damage.

When you contact us, our skilled team will assess the extent of the damage and provide you with expert recommendations. In some cases, repairs may be feasible, where damaged parts can be replaced and the machine restored to working order. However, if the damage is extensive or cost-prohibitive, we can guide you in selecting a suitable replacement model tailored to your needs and budget.

Preventative Maintenance and Winterizing Tips

In addition to draining your pressure washer, there are several other steps you can take to protect it from frost damage during the winter months:

  1. Store Indoors: Whenever possible, store your pressure washer in a climate-controlled environment to shield it from freezing temperatures.
  2. Insulate Exposed Components: If storing indoors isn’t feasible, insulate any exposed components, such as hoses and fittings, using insulating materials or covers specifically designed for pressure washers.
  3. Use Anti-Freeze Solutions: Consult your pressure washer’s manufacturer guidelines and consider using an anti-freeze solution designed for pressure washers. This helps to prevent freezing and damage to internal components.
  4. Regular Maintenance: Schedule routine maintenance and servicing before winter to ensure your pressure washer is in optimal condition. Our expert technicians can perform comprehensive inspections, identify potential issues, and provide necessary repairs or maintenance.


Protecting your pressure washer from frost damage is crucial to avoid costly repairs or replacements. By draining your machine, recognizing the signs of frost damage, and promptly contacting our professional team, you can ensure the longevity and reliable performance of your pressure washer. Don’t let the cold winter temperatures take a toll.
